The AFR-Series uses a circular configuration of up to eight tubular filter housings. Process fluid flows into the housing at the inlet at its base and passes across the filter media from the outside inward. Due to this flow path, contaminants collect on the outside of the filter element slowly forming a cake, removing smaller particles.
During backwash, triggered by time or pressure differential, the flow diverter inside the cleaning valve rotates to the tube to be cleaned. This closes the tube to the incoming process liquid and opens it to the atmosphere (via a drain line). The result causes outlet process liquid to flow in reverse through the element, cleaning it of contaminants and expelling them through the drain at the top of the system. You will notice that we maintain an equilibrium of differential pressure across the filter element due to the elements patented design, thus ensuring thorough backwashing for the entire length of the filter element.
Features:
• Solids removal from 1 to 1,700 microns • Flow rates up to 2,000 GPM (454 m3/hr.) • Broad selection of filter media material • Numerous automated backwash options • Backwashing requires <2% of system volume • Smooth pipe transitions minimize pressure drop • Isolated backwash flow while continuing to deliver filtered product. |
Service Requirements:
WATER: Minimum backwash
water at 45 psig (3 bar).
AIR: (for automatic
units) 60-120 psig (4-8 bar) at 5 CFM (140 dm³/m).
ELECTRICAL: (for
automatic units) 120V AC or 240V AC at 50 or 60 Hz.
